IVIACHINE'FOR FORNING FINGER-RINGS.

SPECIFICATION forming part of Letters Patent No. 455,430, dated July '7,1891.

Application tiled March 16, 1891.

To all whom it may concern:

Be it known that I, WILLIAM H. BECKHAM, a citizen of the United States,and a resident of Port Richmond, in the county of Richmond and State ofNew York, have invented certain new and useful Improvements in Machinesfor FormingFinger-Rings, of which the p following is a specification.

The invention relates to improvements in machines for formingfinger-rings; and it consists in the novel devices and combination ofelements Vdescribed hereinafter, and particularly pointed out in theclaims.

The machine sought to be protected hereby receives the ring or blankformed in the rough by dies or otherwise and transforms it into thecompleted ring of the outline desired. In the drawings I haveillustrated the ringor blank in the rough and also the fmished ring. theniachineit is held on a spindle and caused to revolve rapidly in contactwith and under the direct pressure of grooved rollers, which impart theform and finish to the ring.

The invention will be morefully under-` stood from the detaileddescription hereinafter presented, reference drawings, forming a part ofthis specification.

Referring` to the accompanying drawings, Figure lis a front endelevation of a machine constructed in accordance with the invention;Fig. 2, a top 4view of same; Fig.`3; an enlarged front elevation ofsame, the upper portion being broken away; Fig. 4, a vertical sectionalview on the dotted line ft 4 of Fig. 3.l Fig. 5 is a detached verticalsection on the dotted line 5 5 of Fig. 4. Figs.' 6 and 7 are detachedsectional views of parts of the machine hereinafter specificallyreferred to. Fig. 8 is a plan and sectional View of the blank prior toits submission to the machine which is made the subject of thisspecification, and Fig. 9 represents a plan and section of the finishedring formed by the present machine from the blank illustrated in Fig. 8.

In the drawings, A B respectively designate the ends of the machine,said ends being connected by the tie-rods C and being se-` curely boltedto the floor.

The ends A B of the machine are provided with the vertically-elongatedopenings D, as

'illustrated in Figs..l and 4, which receive the NVhen the blank issubmitted tobeing' had to the Serial No. 385,202. (No model.)

bearing-blocks E, in which are journaled the opposite ends of thedriving-shaft F, which carries upon its front end, adjacent to the outerface of the end A of the machine, the grooved forming-roller G.

Over the driving-shaft F is arranged within the openings D thesupplementary shaft H, which at its rear end is connected by the gearingI with the shaft F, and at its front end is provided with the spindle J,the latter being removable at will, as illustrated in Fig. 7, in whichsaid spindle .I is illustrated as having a threaded inner end to engageacorrespondingly-threaded socket in the front end of the shaft H. Thespindle J is made removable in order that a spindle of appropriate sizemaybe connected with the shaft H for rings of varying diameters.

Over the ends of the shaft H are provided within the elongated openingsD the bearingblocks K, which are caused to firmly bear upon the shaft Hby means of the bearingscrews L. It is obvious that by the operation ofthe screws Il .the bearing-blocks K may be forced upon the shaft H asfirmly as may be desired.

The shaft F is provided at the inner faces of the ends A B of themachine with the collars'M, which operate to retain theshaft F inappropriate relation to the ends A B of the machine. The front end ofthe shaft H'is provided with the collar N, which prevents the shaft frommoving forward through the end A, while adjacent to the rear end of theshaft H the end B of the machine is provided with the bowed plateO,which passes around the rear end of the shaft H, and is provided withthe screw P, the point of which has a bearing against said end of saidshaft H, and prevents the same from moving rearward through the openingD in the end B of the Y machine. By means of the collars M N and theplate O, having the screw P, the shaftsF H are retained in appropriaterelation to each other-and to the ends of the. machine. shaft F extendsoutward beyond the ,end of the shaft I-I, and is provided with .thespurgear wheel Q, which is engaged by the pinion R, mounted upon anauxiliary shaft S, which receives the driving 4or belt wheels T, Thewheels T are adjacent to each other, and the one nearer the pinion-wheelR is rigidwith The 1' TOO the shaft S, while the right-hand one of saidwheels'T is loosely mounted upon said shaft S in the customary manner,the purpose being to provide means whereby thc belt may be shifted fromthe rigid wheel adjacent to the pinion R .in order that the operation ofthe machine may cease without stopping the engine or other motive power.The motion from the pinion-wheelRis imparted through the gear-wheel Q tothe driving-shaft F,and this shaft through the medium of thepinionwheels I causes the rotation of the shaft Il.

Upon the front end of the shaft F,adjacent to the outer face of thefront end A of the machine, is also provided a collar, and against thiscollar is arranged upon said shaft the revoluble ring V, which has thearm "W to receive the inner end of the link X, and against thisrevoluble collar V is arranged a duplicate revoluble collar Y, havingthe arm Z to receive the inner end of thelink ct. The collars V Ycorrespond in all respects with each other and their arms W Z extendupward and outward on opposite sides of the spindle J, as illustrated onan enlarged scale in Figs. 3 and 5. The collars V Y move easily upon theshaft F under the action of the links X a, which also correspond witheach other and carry at their inner ends the rollers b. The outer endsof the links X a are connected, respectively, with the inner ends of thepivotally-secured arms d by means of the pins or bolts e, which carrythe followers f, arranged to move in the curved grooves or guides g,formed in the front face of the end A of the machine. The jointed endsof the links X a and the arms d are connected, respectively, with therods h, whose lower ends meet and are secured by means of a bolt i' withthe lever j, the latter being secured on the bolt k and extending beyondthe lower ends of the rods 7i a sufficient distance to afford a bearingfor the cam m, pivotally secured at n and provided with thecrank-'handle q, by which the cam may be operated at will. The cam m isprovided with the rim 7' to receive the roller s, secured upon the upperend of the arm t, connected with the leverj. During the rotation of thecam m the roller s travels along the surface of the rim o", as indicatedby dotted lines in Fig. 3. The purpose of the cam m and crank-handle qis to afford an adequate means for depressing the outer end of theleverj and thereby drawing downward the connecting-rods h and forcinginward the inner ends of the links X a for the purpose of bringing theirgrooved rollers h against the ring w while the latter is under processof treatment, as illustrated by full and dotted lines in Fig. 3.

As above mentioned, the spindle J is removably connected with the shaftH in order that it may be withdrawn and another substituted, accordingto the diameter of the ring it is desired to finish. rlhe grooved rollerG is alsovremovably secured upon the front end of the shaft F in orderthat it may be Withdrawn and a roller having a groove ofl different sizeor form substituted, in accordance with the finish it is desired toimpart to the ring. rlhe roller G is grooved to correspond with theexterior form it is desired to impart to the ring and is secured inplace by means of the nut 00 engaging the threaded end y of the shaft F.

In the operation of the machine the blank illustrated in Fig. 8 isplaced upon the spindle J, the shaft H having been elevated sufficientlyto permit the insertion of said blank, whereupon the machine is set inmotion, the cam m being turned downward, as indicated by full lines inFig. 3, in order to bring the grooved rollers h against said blank withsufficient pressure to transform the blank into the finished ringillustrated in Fig. 9 Upon the blank being inserted over the end of thespindle J the screws L are crowded down upon the blocks K, therebyforcing theblank closely against the grooved roller G, while at the sametime the operation of the camm, through the medium of the lever j andconnecting-rods h, forces the grooved rollers b firmly against the blankat a point above the contact of the same with the grooved roller G. Themachine being in motion and the mechanism being in the position juststated, the ring will be caused to rotate rapidly against the groovedroller G. and grooved rollers h, and be thereby by them duly finished inthe form outlined by said rollers. The followers f move freely in theguidegrooves g, and hence the movement of the cam m will readily eitherelevate or depress the lever j and connecting-rods h. W'hen the cam m isturned upward to the posit-ion illustrated by dotted lines in Fig. 3,its rim fr will, through the instrumentality of the arm if, elevate thelever j and rods h, and thereby force the outer ends of the links X aupward and withdraw the rollers b from contact with the ring fw, atwhich time, the screws L being loosened, the shaft H may be readilytilted upward sufficiently to permit the withdrawal 'of the finishedring.

The collars V Y are of importance, since, as may be readily seen fromFig. 3 of the drawings, they afford a substantial bearing for,

IIO

the inner ends of the links X a and at the same time permit them to bemoved toward or from the ring w. The collarsVYare close against eachother, and hence in Fig. 5 the collar Y appears in full, while thecollar V is hidden from view, being directly in rear of the collar Y.

It is apparent that the pressure brought against the ring is entirelyunder the control of the operator, since the cam m may be turned to andheld in the position desired. The operation of the cam m may be easilyperformed by the attendant and its action, combined with that of therods 71., arms d, and links X a, is such that a positive pressure may bemaintained or quickly varied or released against the ring w.
